Presentation given at USAB 2008, Fourth International Symposium on Usability and HCI for Education and Work, Graz, Austria, November 2008

ABSTRACT: PowerPoint is one of the most frequently used tools to present multimedia for educational purposes. Nevertheless, little is known about the users' needs when using PowerPoint during lecturing. Our study focused on the presenter's needs in this context of use. We interviewed nine university lecturers from the computer science department by means of a questionnaire. The results show that users require features that are not yet realised with PowerPoint. For example, the control and use of other media should be adequately integrated. Or the navigation within the slide collection should be improved to better meet the users' needs. Based on our findings, we outline required system features and suggest solutions in form of a prototype.

    1. 1. PowerPoint Multimedia Presentationsin Computer Science EducationWhat Do Users Need?Elke I. Reuss, Beat Signer and Moira C. Norriehttp://www.beatsigner.comInstitute for Information Systems, ETH Zurich8092 Zurich, Switzerland USAB 2008, November 21
    2. 2. Motivation PowerPoint is one of the most commonly used presentation tools Little is known about user needs for delivering lectures with PowerPoint Our goal: investigate these user needs and develop an enhanced PowerPoint based presentation toolUSAB 2008, November 21 Beat Signer, bsigner@vub.ac.be
    3. 3. Study Design 9 computer science faculty members, age 25-62  ETH Zurich and University of Zurich Method  structured interviews (on average 37 minutes)  collected a sample presentation from each participant Questions  status quo of PowerPoint in lectures  does PowerPoint satisfy the user needs or what additional functionality is desiredUSAB 2008, November 21 Beat Signer, bsigner@vub.ac.be
    4. 4. ResultsSetup Hardware  laptop (n=8) and tablet PC (n=1)  pointing device: laser pointer (n=7) or stick (n=1)  remote control (n=6) Software  PowerPoint 2007 (n=4), PowerPoint 2004 (n=1) and PowerPoint 2003 (n=4) All participants use PowerPoint since more than 7 yearsUSAB 2008, November 21 Beat Signer, bsigner@vub.ac.be
